Limbsaver has several pads that come close to fitting H&R wood stocks, the model for the SB2-988 USH is one of the prefits that works on some, the #10018 is made for the old style synthetic stock, and the #10011 will work on the new style checkered synthetic stock with modification, of course this info is all in the FAQs, has been for years, best advice is use the templates on Limbsaver's website to compare your stock to see what fits best, H&R wood stocks aren't identical, if you think they are, just try swapping recoil pads, each pad is individually fitted so they aren't the same!
